Wi-Fi routers are some of the hardest-working bits of tech in our homes. In fact, the typical UK household has an average of 18 devices connected at any one time. That’s phones, laptops, smart TVs, doorbells, gaming consoles and tablets all competing for the same signal. Explains why we see that annoying buffering symbol so much!
That's where Wi‑Fi 7 comes in. The latest generation of Wi‑Fi is designed to handle more demanding online activities with less lag. But how does Wi-Fi 6 vs Wi-Fi 7 compare? And what do these numbers mean? This guide breaks down exactly what’s changed to help you figure out if it’s time to upgrade.
What is Wi-Fi 6 and what problems did it solve?
The number after Wi-Fi tells you what generation it is. Each new version is designed to be better at handling internet demands than the one before it.
Wi‑Fi 5 focused on going faster. Whereas Wi‑Fi 6 (also called 802.11ax) tackled connection problems on networks with overloaded with devices.
Two key technologies helped make this possible:
OFDMA (Orthogonal Frequency-Division Multiple Access) lets a router communicate with multiple devices at once instead of handling each one separately.
MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) improves how routers distribute bandwidth across multiple connected devices.
For most UK homes, Wi-Fi 6 does a solid job. However, in more demanding homes with ultra-fast gigabit broadband, multiple 4K streams, gaming, remote working, frequently-photographed cats and lots of smart devices, it can struggle.
What is Wi-Fi 7? The new standard explained simply
While Wi‑Fi 6 helps lots of devices stay online, Wi‑Fi 7 (also called 802.11be) makes them work better when they're all being used at once.
There’s three key parts to Wi-Fi 7:
Multi-Link Operation (MLO)
Most Wi‑Fi devices use one band at a time, which act like wireless lanes for moving data around your home. Wi‑Fi 7 can use multiple bands at once, which gives you a faster and more reliable connection.
This means:
More consistent speeds
Less lag
Better performance during network spikes
More reliable connections in busy homes
Wider 320 MHz channels
Wi‑Fi 7 has channels that are twice as wide as those in Wi‑Fi 6. A channel is the pathway your Wi‑Fi uses to send data between your router and devices. That means more data can travel at once, which helps with bigger tasks like 8K streaming, cloud gaming and large downloads.
4K QAM
4K QAM stands for 4K Quadrature Amplitude Modulation and is one of the technologies that helps make Wi‑Fi 7 faster. It allows more data to be sent with each transmission, which keeps streaming, gaming and video calls all running smoothly.
Built for the next generation of connected homes
Wi‑Fi 7 is designed for homes where more devices are competing for bandwidth than ever before. That's why many of the latest routers and mesh systems like the TP‑Link Archer BE550, ASUS RT‑BE88U, MSI Roamii BE Lite Mesh systems and ASUS ROG Rapture GT‑BE98 come with Wi‑Fi 7 as standard.
Router vs mesh system
A router creates your Wi‑Fi network, while a mesh system uses multiple devices to spread strong Wi‑Fi throughout your home. Routers like the TP-Link Archer AX58 (AX3000) and TP-Link Archer AX12 (AX1500) are great value options. Whereas mesh systems like the TP-Link Deco X1500 and TP-Link Deco X50 cover larger homes reliably.

Where Wi-Fi 7 makes a difference
So is Wi-Fi 7 really worth it? Here’s some ways it really shines.
Online gaming – Wi‑Fi 7's lower latency and Multi-Link Operation can help reduce lag spikes during online matches. This makes it particularly good for console and PC gamers.
Multiple 4K and 8K streams – If multiple TVs and tablets are all streaming at the same time, Wi‑Fi 7 makes sure each device plays smoothly without any interruptions.
Working from home – Wi-Fi 7 can handle several people working remotely and help video meetings and large file uploads all take place without a hitch.
Smart homes – Devices like doorbell cameras, security systems, voice assistants, lighting systems, and other connected appliances stay sharp with Wi-Fi 7.
Large homes with mesh systems – A Wi‑Fi 7 mesh system is a good idea for bigger homes as it can provide more consistent coverage all around. The MSI Roamii BE Lite Mesh WiFi 7 Twin Pack is a great way to make your connection go further.
Do you need new devices to use Wi-Fi 7?
Not straight away. Wi-Fi 7 routers are fully backwards compatible, so your current devices can connect to a Wi‑Fi 7 router as normal. Upgrading your router now means your network is ready whenever the rest of your tech catches up.
So if you want the full benefits of Wi‑Fi 7, you'll need devices that support that standard. Many high-end PCs released between 2024 and 2026 already include Wi‑Fi 7 support. And premium smartphones, such as the iPhone 16 series and Samsung Galaxy flagships are already on board.
Should you upgrade from Wi-Fi 6 to Wi-Fi 7?
The answer depends on your broadband speed and how much you use your network.
Stay with Wi‑Fi 6 if:
Your broadband speed is below 300 Mbps
You live in a smaller home
You don’t have that many connected devices
Your current network is reliable
Consider upgrading to Wi‑Fi 7 if:
You have gigabit or faster fibre broadband
Multiple people stream, game or work at the same time
You have a lot of connected devices
You use a whole-home mesh network
Upgrade now if:
You're buying a new router anyway
Your current router is several years old
You're getting a new gaming or smart home setup
You're moving to gigabit or multi-gig broadband
The good news is that most people can upgrade to Wi‑Fi 7, even if you use the router supplied by your broadband provider. In many cases, you can add a Wi-Fi 7 mesh system to your current broadband setup. Or put your provider’s router into modem mode and connect a Wi-Fi 7 router instead.
